Abstract
The present study entitled 'Innovations in e-Agricultural Extension
Technology (e-AET): Diffusion and adoption of agri-expert systems among
extension professionals in Kerala' was conducted at Thiruvananthapuram district
during 2012-2014 covering 100 extension professionals. Expert systems allows
the use and application of information technology and communications
technology (lCT's) to access and obtain information related to agricultural
production, marketing, distribution, and prices, and the results of agricultural
research, innovations, to raise the level of agricultural production and benefit the
farming community. The present study, therefore, is with the objective to conduct
a systematic appraisal of existing expert systems in agriculture vis a vis their
diffusion among the extension professionals.
The findings demonstrate that most of the extension professionals either in
State Department, NGO or University have positive attitudes towards expert system.

content, availability, accuracy and timeliness affect extension professionals' attitudes.

systems, it was found that 10 per cent of the sampled respondents belonged to
innovators category, 19 per cent respondents belonged to early adopters' category, 32
per cent respondents belonged to early majority category, 24 per cent respondents
belonged to late majority category and 15 per cent respondents belonged to laggards'
category. Effectiveness index of expert system applications was worked out using
seven statements and the results showed that pedagogy (as a means to effective
learning through expert system) having highest effectiveness index. The findings
demonstrate that most of the respondents belonged to middle age category, holding
